SHORT-PERIOD VARIABLES IN THE SMALL MAGELLANIC CLOUD CLUSTER NGC-330

In this paper we present results of intensive CCD monitoring of the blue globular cluster NGC 330 in the SMC. From 137 V frames on six nights, we found many short-period variables. Most of these occur among the B-type stars. Since the cluster is very rich in Be stars, we surmise that they are periodic Be stars (lambda-Eri variables). A few eclipsing binaries, including an early-type contact binary, were found. We found a Cepheid with a 1.19-d period, one of the shortest known in the Magellanic Clouds. We also found some short-period late-type variables which cannot be classified. An interesting result is the absence of any beta-Cep variables with an amplitude in excess of 0.02 mag. This could be due to the low metal abundance or presumed rapid rotation of the early B-type stars.
